Advanced Bandwidth Management

Bandwidth management configuration is based on policies that specify bandwidth limitations for traffic classes. A complete bandwidth management policy consists of two parts: a classifier and a bandwidth rule.

A classifier specifies the actual parameters, such as priority, guaranteed bandwidth, and maximum bandwidth, and is configured in a bandwidth object. Classifiers identify and organize packets into traffic classes by matching specific criteria.

For information on using Bandwidth Objects in Access Rules, App Rules, and Action Objects, see Firewall Settings > BWM .

Configuring Bandwidth Objects

NOTE: You also can configure bandwidth objects in an Access Rule as described in Enabling a Bandwidth Object in an Access Rule and in an Action Object as described in Enabling a Bandwidth Object in an Action Object .

To add or configure a bandwidth object:

1	On the Dell SonicWALL Security Appliance, go to Firewall > Bandwidth Objects.

2	Click the Add button to create a new Bandwidth Object.

or

Click the Configure button for the Bandwidth Object you want to change.

The Add/Edit Bandwidth Object window displays.

3	Click the General tab.

4	In the Name field, enter a name for this bandwidth object.

5	In the Guaranteed Bandwidth field, enter the amount of bandwidth that this bandwidth object will guarantee to provide for a traffic class and then select the rate, kbps or Mbps from the drop-down menu.

6	In the Maximum Bandwidth field, enter the maximum amount of bandwidth that this bandwidth object will provide for a traffic class and then select the rate, kbps or Mbps from the drop-down menu.

7	The actual allocated bandwidth may be less than this value when multiple traffic classes compete for a shared bandwidth.

8	From the Traffic Priority drop-down menu, select the priority that this bandwidth object will provide for a traffic class. The highest priority is 0 Realtime, the default. The lowest priority is 7 Lowest.

When multiple traffic classes compete for shared bandwidth, classes with the highest priority are given precedence.

9	From the Violation Action drop-down menu, select the action that this bandwidth object will provide when traffic exceeds the maximum bandwidth setting:

•	Delay, the default, specifies that excess traffic packets will be queued and sent when possible.

•	Drop specifies that excess traffic packets will be dropped immediately.

10	In the Comment field, enter a text comment or description for this bandwidth object.

11	Select the Elemental tab.

12	Under the Elemental Bandwidth Settings heading, select the Enable Per-IP Bandwidth Management option if you want it. The Maximum Bandwidth option becomes active.

1	Enter the Maximum Bandwidth value. The default is 0.

2	From the drop-down menu, select the rate as either kbps or Mbps.

NOTE: When enabled, the maximum elemental bandwidth setting applies to each individual IP under the parent traffic class.

NOTE: For information about these options, see Elemental Bandwidth Settings .
